It really depends upon what you want to do with the knowledge. If you'd like to go out and teach PDC's eventually, then you'll want to look for someone certified. If you just want to get the knowledge and have some fun, then there's absolutely no reason to go anywhere other than the place you want to go, certification or not. Denying yourself that opportunity would be like saying that only PDC graduates are allowed to read the hugelkultur thread. If the knowledge is there, it works whether or not it's Mollison-approved.
Price should also be a factor. If you're paying the same amount of money as an official course, then why not just go get the fun certificate? If it's significantly cheaper, that might be something to sway you in the direction of the bootleg course. If you never plan to use the word "permaculture" in any formal capacity, then having permission to do so is unnecessary.
To me, this is also similar to the USDA organic certification. The certification says something, but there are better options out there that don't include the little green-and-white label. That doesn't undermine the USDA (as much as I'd like that to be true) and you still get good quality food. A farmer who doesn't seek the organic label is in the same boat. She won't get the perks of having the label, like being able to put the logo on her wares and being able to say "organic" in reference to her stuff, but if none of that matters, then who cares?
Figure out what you want to do with the knowledge, learn a little more about your instructor, and I think the answer will fall into your lap. Hope that helps!
